To resynchronize the front and surround chan- nels, follow these steps:
1.Measure the distance from the listening position to the front speakers.
2.Measure the distance from the listening position to the surround speakers.
3.Subtract the distance to the surround speak- ers from the distance to the front speakers.
a.When setting the delay time for the Dolby Digital surround modes, the opti- mal delay time is the result of that sub- traction. For example, if the front speak- ers are ten feet away and the surround speakers are five feet away, the optimal delay time is figured as 10–5=5. Thus, in this example, the delay time for Dolby Digital should be set at five milliseconds.
b.When setting the delay time for the Pro Logic mode, take the result of the sub- traction and add 15 to obtain the opti- mal delay time. For example, if the front speakers are ten feet away and the sur- round speakers are five feet away, the optimal delay time is figured as 10–5+15=20. Thus, in this example, the Pro Logic delay should be set at twenty milliseconds.
NOTE: The DTS, Logic 7, Hall and Theater modes use a fixed, nonadjustable delay time.
The Dolby Digital mode also includes a separate setting for the center channel delay mode, since the discrete nature of these signals makes the location of the center channel speaker more critical. To calculate the delay for the center channel, measure the distance from the pre- ferred listening position in the center of the room to both the center channel speaker and either the left or right speaker.
If the distances are equal, no further adjustment is required and the center delay should be set to zero. If the distance to the front speakers is greater than the distance to the center speaker, you may wish to reposition the speakers by moving the front left and front right speakers closer to the listening position or the center speaker further away from the listening position.
If repositioning of the speakers is not possible, adjust the center delay time, adding one milli- second of center channel delay for every foot
closer to the listening position the center speaker is than the front speakers. For example, if the front left and front right speakers are each 10 feet from the listening position and the center channel speaker is 8 feet away, the delay is figured as 10–8=2, suggesting an optimal center delay of 2 milliseconds.
To set the delay time for a specific input, continue within the SURROUND SETUP (Figure 4) menu. If the system is not already at that point, press the OSD button v to bring up the MASTER MENU; press the Û but- ton q and then the Set button o to bring up the SURROUND SETUP menu, and then press the Û button q once.
If the Dolby Digital mode is selected, the Ý cur- sor will stop at the CENTER DELAY line. In that case, press the Ü/Ý buttons n 31 until the number calculated using the formula shown above appears in the display. When the CENTER DELAY is entered, press the Û button q once to move to the next line.
When the CENTER DELAY is set, or if the Dolby Pro Logic mode is selected, the Ý cursor will be at the SURR DELAY line so that the delay for the surround speakers may be set. Press the Ü/Ý buttons n 31 until the num- ber calculated using the formula shown above appears in the display. When the delay settings are complete, press the Û button q once to move to the next line.
Note that the delay settings may also be adjusted at any time when the Dolby Digital or Dolby Pro Logic modes are in use by pressing the Delay button on the front panel ñ or remote 30 , followed by a press of the Set button o. Next, press the Ú/Û buttons mq on the remote or the Selector but- tons 5 on the front panel until the desired figure appears in the Main Information Display X.
Night Mode Settings
The Night mode is a feature of Dolby Digital that uses special processing to preserve the dynamic range and full intelligibility of a movie sound track while reducing the peak level. This prevents abruptly loud transitions from disturb- ing others, without reducing the sonic impact of a digital source. Note that the Night mode is only available when specially encoded Dolby Digital signals are played.
To adjust the Night mode setting for an input
from the menu, make certain that the Ý cursor is on the NIGHT line of the SURROUND SETUP menu. Next, press Ü/Ý buttons
n31 to choose between the following settings, as they appear in the on-screen display:
OFF: When OFF is highlighted, the Night mode will not function.
MID: When MID is highlighted, a mild com- pression will be applied.
MAX: When MAX is highlighted, a more severe compression algorithm will be applied.
We recommend that you select the MID setting as a starting point and change to the MAX setting later, if desired.
Note that the Night mode may be adjusted directly any time that a Dolby Digital source is playing by pressing the Night button k. When the button is pressed, the phrase D-RANGE will appear in the lower third of the video screen and in the Main Information Display X. Press the Ú/Û button mq within three seconds to select the desired setting.
When all settings for the surround setup have been made, press the Ú/Û buttons mq so that the Ý cursor is next to RETURN TO MENU, and press the Set button o to return to the main menu.
Speaker Setup
This menu tells the AVR 210 which type of speakers are in use. This is important as it adjusts the settings that determine which speakers receive low-frequency (bass) informa- tion. For each of these settings use the LARGE setting if the speakers for a particular position are traditional full-range loudspeakers that are capable of reproducing sounds below 100Hz. Use the SMALL set- ting for smaller, frequency-limited satellite speakers that do not reproduce sounds below 100Hz. Note that when “small” speakers are used, a subwoofer is required to reproduce low frequency sounds. Remember that the “large” and “small” descriptions do not refer to the actual physical size of the speakers, but to their ability to reproduce low frequency sounds.
If you are in doubt as to which category describes your speakers, consult the specifica- tions in the speakers’ owner’s manual, or ask your dealer.
